FEED-TABLE FOR HAMVMERlsNG-MAOHINES.

SPECIFICATION forming part of Lettersllatent No. 293,611, dated February 12, 1884. j. Application filed September 26, 1883. (No model.)

To all wlwm t may concern:

Be known that I, W. DEWEEs WOOD, a citizen of the United States, vresiding at Pittsburg, county of Allegheny, State of Pennsyli feed-table, the upper part of the hammer being removed and the hammer-frame being shown in section. Fig. 2 is an end view of one-half of the table. Fig. 3 is a side viewv of one-half of the table, the gear-wheels and idlers being indicated by dotted lines to show their relative arrangement.

It is necessary, as the final step in the manufacture of Russia orplanished sheet-iron, that the sheets should be subjected in packs to an equal and uniform hammering one or more times over the whole surface, in order to produce the bright polished surface characteristic of this kind of sheet-iron. It has been found necessary, in order to produce good and uniform results in this hammering operation, to use a hammer the face area of which is v considerably less than the. area of the sheets to be hammered, that is less in length and width; consequently, in the use of such a hammer, it is necessary to move the packs of sheet-iron longitudinally andl transversely across the anvil of the hammer in order to bring every part of the sheet under the actionof the hammer.

My invention relates to feed-tables to be used in connection with a suitable hammer, for the purpose of moving the packs horizontally and transversely across the hammer and at any desired speed, and as far at each movement as may be desired; and to this end my invention consists, in general terms, of aseries of suitably-driven feed-rolls mounted on carriages located one on each side of the hammer or anvil, and constructed to moveback and forth along the sides of the hammer on suitably-arranged Ways.

A indicates the anvil, and a the standard, of a power-hammer suitable for the purpose, the

the frame O'r bed c', and to this frame or bed are attached the side bars, d, which are rendered more rigid by rods d', which extend across the carriage and through the side bars, nuts being screwed upon therods against the side. bars. In these-sidebars, d, are mounted the shafts of the feed-rolls e, the bearings of the shaft being lengthened by flanged collars d2, bolted onto the inner side of the side bars, d, as shown by sectional view at the left hand of Fig. 1. At the end of the table toward the anvil is bolted to the side bars, d, the transverse b'ar f, which prevents the sheets of the pack from sagging down between the last feedroll and the anvil. the longitudinal bars g, which pass along the grooves e in the feed-rolls c and prevent the .sheets from sagging down into said grooves, which are formed inthe rolls for the purpose of receiving the two prongs-1 2 of the lifting device H, which. is used for placing the pack on the feed-rolls. These longitudinal bars g are further supported by the rods d', which pass through them, the bars being retained in place by nuts on the rods.

On the shafts of the feed-rolls, which project beyond the side bar, d,.on one side of the carriage, are mounted gear-wheels h, which mesh with idler-gears Il, mounted on the side bar, d. Through one of these idler-gears h passes the shaft k, the gearA and shaft being so splined together as to allow Vthe gear to move longitudinally on the shaft, but to revolve with it. One end of this shaft lc is mounted in suitable bearings, Z, and has keyed to it between these bearings Z a pinion, m, which meshes with a pinion, n, on a short shaft, o, mounted in bearings p. This shaft o is also provided with another gear, q. `To revolve this gear g, and by means of it, through the shafts and 'gears described, the feed-rolls c, first in one direction and then in a reverse direction, a rack, of, sliding on ways fw, which'are provided Attached to'thisbar'f are IOO with friction-rolls s, is reeiprocated back and l the feed-rolls, the prongs of the lifting device forth by a hydraulic ram, D, Whose pistonrod is connected with the rack. This rack is connected to a similar rack, r', and gives the requisite movement to the mechanism corresponding to that above described mounted von the other carriage, C. To give to the carriage the transverse motion, a yoke, E, secured to the piston-rod of a hydraulic ram, (not shown, but similar to that shown at D,) is attached to one side of each of the carriages C C by beams t 1. To relieve the beams t t of the weight of yoke E, the center of the yoke is supported by rollers a; on rails y. By the above mechanism a transverse motion is given to the carriage. Secured to the standards a., and extending from said standards to each side of the anvil, are plates a', which support the pack on each side of the anvil and between the rolls of the carriages.

It will be observed that the feed-rolls of the carriages and the carriages themselves have a simultaneous and equal motion in like dircctions, the feed-rolls moving the packs longitudinally of themselves across the anvil, and the carriages carrying the packs transversely across the anvil or across the line of feed, and -that both motions may be reversed by a reversal ofthe strokeof the pistons.

The side bars, d d, of one of the carriages may be extended, and, passing by the anvil, be united to the bars d d of the other carriage, and the gearing of one carriage be connected to that ofthe other carriage by a train of idlergearing, and in such a construction only one of the racks T i" would be necessary, and the shafts and gears now used to transmit motion to the gears on one of the carriages would also be omitted.

The operation of the apparatus is as follows: The packs are taken, upon the prongs of the lifting device, and by them deposited upon dropping into or passing along the grooves of the feed-rolls, and on being relieved of the Weight of the pack are easily Withdrawn. The feed-rolls are then set in motion by the hydraulic ram D, feeding forward the packs underthehammer. Thenthecarriagesare moved, carrying the packs transversely under the hammer, and by alternating these movements of the rolls and carriages, or reversing, if necessary, every part of the surface of the packs is successfully presented to the action of the hammer, and the operation is repeated or continued as often or as long as may be desired.

lVliat I claim as my invention is- 1. In a machine for hammering sheet-iron, the combination of the anvil A, the reciprocating carriages C C, the rolls c, mounted in said carriages, means for reciprocating said carriages, and means for rotating the feedrolls, substantially as shown and described.

2. In a machine for hammering sheet-iron, the combination o' the anvil A, the reciprocating carriages C C', the feed-rolls e e, mounted in said carriages, the gear-wheels 7L, and idlers h, the reciprocating rack r, means for transmitting motion from rack to the gears and idlers, and means for reciprocating the carriages, substantially as shown and described.

3. The combination of the carriage C, the feed-rolls c, provided with grooves e', the longitudinal and transverse bars g f, the gears and idlers h and h', and the means for rotating said gears and idlers, substantially as shown and described.

In testimony whereof I have hereunto set my hand.
